United States Patent O' 3,132,445 FLASH@ @RAVEL f'iil AND FASGEA Eiiiiord D. Swanson, Zidi Wellesley Drive, Lansing llt), Mich. Filed Nov. le, lenti, Ser. No.. 63,924 6 tlaims. tti. :Sii-m66) The invention relates to building structures and refers more speciiically to a method of and means for constructing the periphery of a roof or the like whereby improved weatheiprooiing is provided and finishing members are protected during construction.

In the past leaking of substantially flat roofs about the periphery thereof has been a particular problem in the construction industry. Leakage occurring specifically at the overlap of the felt flashing and the fascia member is primarly caused by defects in the cohesion between the two dissimilar materials of the hashing and fascia which on movement between the ilashing and fascia produce breaks in the flashing felt allowing waterto penetrate the roof at this point.

in addition the constructing of roofs in the manner above indicated often results in the pitch being splashed on the fascia members during the mopping operations. The pitch is extremely diicult to remove from the fascia members and often leaves permanent stains thereon.

It is therefore one of the objects of the present invention to provide means for constructing7 the periphery of a roof having improved weatherprooiing characteristics which means is operable to protect the fascia members during construction.

Another object is to` provide a method of constructing the periphery of a roof whereby improved weatherproofing characteristics are provided and the fascia members of the roof are protected during construction.

Another object is to provide a positive watertight seal between a flexible flashing and a fascia member which seal will still allow dissimilar movement to occur between the fascia and dashing, said movement being absorbed by and/or compensated for by the seal without the seal losing its waterproofing abilities.

Another object is to provide means for constructing the periphery of a roof comprising a fascia member adapted to be secured around the periphery of the roof and including a gravel stop portion, a iiashing having two separate portions adapted to be integrally included with roofing material fat diiiere'nt times during the construction of the roof periphery and a key strip for securing the lilas-hing to the fascia-member.

Another object is to provide structure as set forth above wherein the fascia member is constructed entirely of plastic and has the exposed surface thereof serrated to reduce the sheen thereof.

Another object is to provide structure as set forth above wherein the fascia member may be installed on a root' having extending eaves or at the top of a substantially vertical wall.

Another object is to provide structure as set forth above wherein the hashing is a flexible plastic sheet, one portion of which is a short fiap adapted to be secured directly to the roof decl( and the other portion of which is a long iiap particularly adapted to be mopped into the upper layers of felt of a pitch and gravei roof.

Another object is to provide a method of constructing a roof comprising attaching a liexible dashing to a fascia member so that the flashing has a lower short fiap and an upper longer flap securing the fascia member to the periphery of the roof being constructed, fastening the short iiap to the root surface to be finished, covering the short lap with the roong and adhering the long iiap to the top of said rooting.

3,132,445 Patented May 12, i964 Another object is to provide a method of constructing the periphery of a roof as set forth above wherein during the securing oi the short tlap to the roof surface and the constructing of the roof material over the short flap, the long flap is folded over the fascia member to protect the fascia member during the construction of the roof.

Another object is to provide a method of and means for constructing the periphery of a roof which is simple, economical and eiiicient.

Other objects and features of the invention will become apparent as the description proceeds, especially when taken in conjunction with the accompanying drawings, illustrating a preferred embodiment of the invention, wherein:

FIGURE 1 s a section View of the periphery of a roof constructed in accordance with the invention taken substantially on the line -l in FIGURE 2.

FIGURE 2 is a partly broken away plan view of a portion of the periphery of the roof shown in FIGURE 1 with the roofing material removed taken in the direction of arrows 2-2 in FIGURE l and particularly showing the lap joint of the upper flap of the flashing and the butt joint of the lower iap thereof.

FIGURE 3 is a section of the gravel stop portion of the flashing member shown in FIGURE 1 illustrating the method of securing the dashing to the fascia member.

FIGURE 4 is a cross section of the periphery of a roof construction wherein the fascia member is secured to a substantially vertical wall taken along the line 4 4 in FIGURE 5.

EIGURE 5 is an elevation view of a portion of the periphery of the roof structure shown in FlGURE 5.

With particular reference to the drawings one` embodiment of the present invention `will now be disclosed.

As shown best in FIGURE 1 the periphery of -a builtup pitch and gravel roof l@ is formed by a fascia member 12 secured to the yfascia board 1d in conjunction with the flexible iiashing 16 secured to the fascia member l2 b j means of a key strip 13. The construction as shown provides a roof periphery having an -upper and lower seal whichpis not subject to leaking due fro waiter collecting in air pockets fonmed between the sheets of rooting felt 2t). Further in accordance with the method of constructing the roof periphery illustrated .in FIGUR-E 1 the fascia member 1,2 is protected during `the construction.

More specioally the roof construction shown in FIG- URE 1 comprises the upper end of a wall 22, joist meinber 24 extending outwardly therefrom, the roofing boards 26 and lthe fascia board 14 secured over the ends of the joists '24 4and rooting boards V2d as shown. 'Ilhe inclined member 30 is provided between the roong boards 26 and fascia member 28 so that drainage will generally be inwardly of the roof -in the usual manner. While one particular roof structure is illustrated it will be understood that similar structures having the same `general conguration, such as structures using metal trusses and root declis may have the periphery of the roof constructed in accordance with the invention.

rifhe roong material to be applied over the roof boards Z6 includes [the rooiing felt 20 usually applied in from three to six layers, each layer Ibeing mopped in with pitch. A liberal layer of pitch 34 is yapplied over the: last layer of rooting felt and gravel 36 is spread over the pitch layer. lit will be understood that substantial variation in the particular roof material is ialso possible within the scope of the present invention.

The fascia member 12 in .accordance with the invention may be yan extruded plastic strip varying in length and having the general cross section indicated in FGURE l. T e plastic fasci-a stnip may be extruded :from well known resinous materials, such as Geon 8700 or Cyco'lac. A substantially unplasticized Geon material has been used plastic whereby the fascia strip is more pleasing in appearance. Further the plastic strip may be of substantially any desirable color.

The .fascia member 12, as shown in FIGURE l, is provided at the bottom thereof with a nailing ange 40 Whereby the fascia member l2 is secured to the fascia board 114 by means of nails 4t2 and further includes the drip ledge 44. At the upper end of the fascia member 12 as shown the gravel stop 46 is `formed therein having the pocket 43 in which the flashing 16 is secured by the key strip I8.

A modified fascia member 12a is illustrated in FlG- URE 5 which is particularly adapted to be secured to building structures lhaving vertical walls 50 to which it -is desired to secure the fascia member lZa. The cross section of the fascia member 12a is similar to that of the fascia member 12 except that the drip ledge 44a includes the -recess S2 there-in to which the end 54 of a bracket 56 which is secured tothe wall 5d by convenient means, such as screws 58, is inserted to secure the lower portion of the fascia member l'lZa to the wall Sit. `If desired the fascia member 12 may be formed `with a recess, such as 52, in the drip ledge 44 whereby the flange dit may be cut therefrom to produce the fascia member 12a so that -a single fascia member may be provided for all jobs.

The flashing 16 as shown best in FIGURE 1 is a flexible plastic material, such las the well known Nervastral or Saraloy having a Durometer A Scale hardness of approximately 60, a `tensile strength of 900 pounds per square inch, an ultimate elongation of 350% and a specific gravity of 1.52.

As shown the flashing i6 is folded to provide a short flap 6i) and a long lap 62. The short flap 6@ is secured to the member 3d by convenient means, such las nails 6d. The long flap 62 is secured to the roofing by means of mopping the long flap into the pitch 34 on top of the last layer of roofing felt 2t). With such construction there is practically no chance of leaks forming Aat the periphery ofthe roof iti since a dou-ble seal is provided thereat both above and below the roofing felts. rllhus even if air bubbles do form in the periphery of the roof It? water will not collect therein to form leaks.

-ln addition the short llap 60 provides a stop for the pitch `as the rooting felts are being mopped in place around the periphery of the roof. Further the long llap 62 during the mopping in `of the roofing felts Ztl may be thrown over the exterior of the `applied `fascia member l2, as shown in `dotted `line in FIGURE l, and in such position prevents the pitch slopped over the edge of the roof during mopping in of the felts from contacting the fascia member l2.

The flashing 16 is ysecured within the pocket 43 in the fascia member 1.2 as shown best in FIGURE 3 by means of the key strip 18 after folding 4the flashing 16 to provide the long and short flaps as desired by merely inserting the flashing lo yand key strip 1S in the recess 43 and pivoting the key strip 13 in the direction of the arrow 66 whereupon tbe key strip 18 is locked in position behind the projecting portion 68 of the gravel stop portion 46 of fascia member I2.

In installation the flashing 16 is first secured to the fascia member 12 in the manner shown in FIGURE 3 by means of the key strip 18. The portion 60 of the flashing 16 is then secured to the periphery of the roof to be finished as shown in FIGURE 1 by the nails 64 or other convenient means. The long flap 62 is then folded over the fascia member 12 as shown in FIGURE 1 to protect the fascia member l2 during the mopping in of the building felts 2l). The building felts 20 are then mopped in place with pitch and the long lap 62 is laid on top of the [l last building felt 2d and a layer of pitch 34 is poured thereover followed by the spreadingof the gravel 36.

At joints around the periphery of the roof the short flap 6? is cut off even with the edge of a length of fascia member i2 while the long flap is extended from the ends of both abutting fascia members 12, as shown in FIG- URE 2. The long iiaps 52 are then overlapped and sealed with solvent mastic. A short plastic coupling member may be secured over the abutting ends of the fascia member l2 if desired, as shown in FIGURE 5, to complete a joint. It will be obvious that the key strip 18 may either be cut olf at the end of the abutting fascia members 12 or continued through the joint as desired.

The drawings and the foregoing specification constitute a description of the improved plastic gravel stop and fascia in such full, clear, concise and exact terms as to enable any person skilled in the art to practice the invention, the scope of which is indicated by the appended claims.
